Crimson Queen Japanese Maple Turning Green: Excess Nitrogen or Shade

Red Leaf Color Loss in Young Maples

Green leaves on a red cultivar usually mean too much nitrogen (from manure/fertilizer) or insufficient sun. Young trees often green up temporarily.

Fix

• Stop fertilizing for 2 years.
• Water deeply (1 in. weekly) to flush excess N.
• Ensure 6+ hours direct sun.

Color should return as tree matures and N balances.
